First we need to simplify 
to 0.003.
We get 3000(1+0.003)
Now we simplify 1+0.0031+0.003 to 1.0031.003.
3000×1.00
Simplify {1.003}^{72}1.003 to 1.2407011.240701.
3000×1.240701
Then we simplify to <u>3722.103387.</u>

6. D
7. B
Step-by-step explanation:
Nancy takes a test that has two sections: essay and true/false. She scores 56 points on the essay. Each true/false question is 4 points. So x number of true/false is worth 4 points each or 4x.
Together her score will be 56 + 4x.
She wants to score more than 80 or > 80.
So her test can be represented as the inequality 56 + 4x > 80.
This is solved using inverse operations.
56 + 4x > 80
4x > 24
x > 6
This should be graphed as an open circle at 6 on the umber line pointing and shaded to the the right for numbers greater than 6.
